To: Ultrasound Daily Digest Hi netters, sounders, etc. I have two questions, which I thought you could maybe answer. When I read the announcements on EPAS there was a statement, that the 16 bit recording option will be able to recored 16 bit stereo at 48 kHz. Now my question: As far as I know the GUS does only supply 16 bit stereo 44,1 kHz playback, so what should we do with those 48 kHz samples????? Another question is: Are there any future plans for extended versions of the card (for example: supporting 4 or 16 MB on board memory, or any other improvement), or is there the possibility of any hardware faults, which might result in corrected hardware versions? Or is the GUS which is available now the one and only version of sound hardware produced by Gravis in the near (or even not near) future?

To: Ultrasound Daily Digest That's right! Well, sort of. It seems that Sierra is starting to release of their new games with a Windows EXE that allows you to play their games in Windows using the Windows drivers. That means that if you have an Ultrasound driver for Windows (an you should) then Sierra is essentially supports the Ultrasound. The first game they've release with the Windows version is Ecoquest II (although I've heard that a beta version of Space Quest V had a really buggy one-I don't know if it was in the final version). Anyways, I had a little trouble getting it to work at first, but what I had to do was select extended MIDI device (or whatever they call it) in the install program (you must run SETUP.EXE from Windows for the Windows install). Then, before I run the game, I select Control Panel, chose Midi Map, and then select "Ultrasound-?k" (with ? being the amount of DRAM you have installed). Then, I ran the patch loader and loaded the patches for "LOAD?.MID" (with ? being the amount of DRAM you have again). I don't know of any of this is unnecessary, but it worked for me. And don't think that you need a meg of DRAM to get good results, because you don't -- I still only have 256k and it sounds great (a lot better than SBOS!).

A copy of it was inside the box of the last GUS I received via Gravis' offices in Washington. I think it can be had by contacting Gravis for $14, and it is WELL worth it! The sound is superb (16 bit, stereo, original patches) and the gameplay is great too. As for other titles supporting GUS, they are coming. There will be Miles MIDIPak/DIGIPak drivers for the GUS within a short time, and these will make it simple for developers to add GUS support (unfortunately it's not as good as writing your own GUS support but it will sound as good as the MIDI demo I would think) and the drivers will also be usable with games already out there that use Miles drivers. Aside from the Miles drivers, I know of 5 titles that will definitely have GUS native mode support that are in development. There are most certainly many more in development, but these are the ones I know about since I'm involved with them. Another thing that looks good for the GUS - everyone I have talked to says that everyone they've talked to seems really interested in MODs and MOD-like formats due to the sucess of Star Control II. What does this mean for you? Well, if a company decides to use MOD-type music in a game, I would say the chances of GUS support in that game are at least 99%. The GUS is the best device currently available for playing MODs, and the developers tend to demo their stuff with the best equipment, such as Sierra using Sound Canvases for midi. Can't play a MOD very well on a Waveblaster! :) - Dan ________________________________________________________ Dan Nicholson - PCkS Associates - (908)964-8066 - ModDan 553 Thoreau Terr.

GMOS will still have to support dynamic patch loading. GMOS will write the .cfg file in descending order of most frequently accessed patch. This will guarantee a better fit at the start. But still dynamic patch loading WILL have to be supported. In this case, if GMOS finds that the patch required is not in one of the buffers in memory, it will load it off the disk, so there will be a slight slowdown there. Note that the .cfg file is not a catch-all. It is simply there to help GMOS select the most appropriate patches to load without having to wait all the time for the dynamic patch loading. > tonight...) then all we have to do to implement GMOS is to add digital > SB support without losing GM ability.

The purpose of running a SB in the same machine as the GUS is that you don't want to use SBOS at all! SBOS won't use DMA channel 1 if it isn't installed and the diagnostics run just fine unless you select the SBOS compatibility test (which is irrelevent if you aren't going to use SBOS). Please understand I am NOT being critical of SBOS - I can appreciate the amount of work that has gone into it and I think it does a reasonable job given the constraints (i.e. it is an emulator). Many games run just fine with SBOS but you just can't cover all bases, particularly when performance is an issue. What I do NOT understand is why Gravis seems to want to insist on being the ONLY sound card in my computer. If enough GUSes are sold that they become heavily supported then I may eventually (and with great pleasure) discard my co-resident SBPro but in the meanwhile it stays. FWIW I have modified my GUS so there is absolutely no conflict with the SB/Adlib at all. It is a very simple change that I will be glad to share with you if you want - you may want to offer it as an inexpensive (free even) option to purchasers who already have other sound cards.

It seems to be clear now that Advanced Gravis will include MidiSoft Recording Session and Power Chords with the new installation disks that will be shipped out to all registered customers within shortly. Recording Session is a nice sequencer program running under Windows. Ballade, however, will probably be a problem to use with the UltraSound, as it relies on direct communication with the hardware (the MPU-401 interface). This will ( generally) not be the problem with any Windows-based sequencer, however, as they will utilize the Multimedia Extension to communicate with the hardware via the soundcard's driver software. -=* Bjorn ------------------------------ Date: Tue, 30 Mar 93 07:00:51 PST From: RICH CATENA DTN 321-5170 Message-Id: <9303301459.AA04945@enet-gw.pa.dec.com> Subject: GUS and dos 6 To: Ultrasound Daily Digest Since it will be on sale late tonight or tomorrow, has anyone tried SBOS 2.04 with dos 6 beta?

After about three hours, I found that if I want my SB to always works proprely, I have to put it in BASE 220, IRQ 7... and to put the GUS in an other configuration with an other DMA chanel (like 3 for example). But here, I had some problems with some games (old games like Bubble Bobble, or new games like Wolfenstein 3D in SB, or ZONE 66 in GUS mode...): my first aim was to have the GUS work properly, so, I decided to leave the old configuration and to put the SB in BASE PORT 240. Then, here is how my cards are: SB: 240, int 5, dma 1 GUS: 220, int 7, dma 3, midi 11 AND IT WORKS FINE!! I read in the GUS user manual that "we can't have both an Ultra Sound and Sound Blaster or Adlib" but it's not realy true... But... there's a BUT: the SB will work fine only if the game or the software reads the environnement varialable or if we can define where is the SB (i.e. Base port and Int): in one week I only have 2 problems.... Bubble Bobble & Wolfenstein. But I simply execute SBOS then it works. Last of all, if a game like Tetris Classic doesn't work, I force it to play in ADLIB and that's it! What I want to say in this is two things: is there somebody who has a better succes to put these two cards at the same time? (i.e. to have ALWAYS the SB which works correctly) If yes, please, leave me a message... Second, with this, I have a ratio of 95% of games which works correctly with no slowdown... so, bye an old SB if you want more compatibility (a had mine at 50$!).

Also, it seems that the UltraDox might not contain enough information. Here are some of the proposed GMOS "features": 1. A 1MB GUS would be required, 64K reserved for SB DAC emulation (if we can get the information from Gravis/Forte) and the rest for patches. 2. A hardware/software combo. Software being a TSR, and the hardware portion is a simple loop back from the MIDI out to the MIDI in (or to the serial port). Can some hardware guru check out this portion? I am not too sure about whether a circuit is needed or we can simply loop with a wire (doubtful). 3. Ability to load patches dynamically into several fixed sized buffers in memory. A patch can span multiple buffers. This will make dynamic memory management of the GUS memory easier. Buffer size can only be changed at startup. In the UltraDox, Josh mentioned that he couldn't get the GUS to load patches while playing back, but someone (Francois Dion?) did mention that it was possible. Anyone have info on this? 4. Ability to intelligently determine the patches that have been used in a particular session and save it as a .GMC file that can be used to tell GMOS which patches to load at startup. This file will be plain text and will be user-editable so hackers can customize it :) 5. Anyone knows where to get the complete set of MIDI commands? 6. If anyone has the sysex commands for the MT-32 and SCC-1 please post.

However, for my GUS to be useful longer term to me I'll need an NT driver for it. Is this in anyone's plans? By all means get the DOS/Windows SW in good shape first, but I really think NT is *way* more interesting and important than OS/2, and is going to be on *ALOT* of desktops real soon (I heard something about 70000 March Beta copies were sent)... For now, when I'm running it on my machine I have no sound (sigh) from my nice GUS (but things seem to run fine, so the GUS isn't making NT angry - I guess that's a feature ;-) - Bob Beck (rbk@sequent.com) ------------------------------ Date: Tue, 30 Mar 93 14:55:14 EST From: tmcreek@eos.ncsu.edu Message-Id: <9303301955.AA21063@c00313-11pa.eos.ncsu.edu> Subject: Ultima 7 part II fix To: Ultrasound Daily Digest Someone posted saying that they kept getting dumped out of Serpent's Isle to a 40 column screen. Well, I had that problems too (with parts 1 and 2) until... I checked the static directory to see what sound drivers it was using. If you set it for SoundBlaster (as we who run SBOS must), you will notice some .adv files. ".adv's?", I asked. "Those look familiar!" I looked in both my installed copy of Monopoly Deluxe and BattleChess 4000, and lo! I found .adv's!!! So I copied sbdig.adv and sbfm.adv from BC4000, ran SBOS and sure enough it worked! The point: you need new .adv's. If anyone out there needs these two files I would be more than happy to upload them to epas, or uuencode and mail them. They are not very big. P.S. If you want to see the endgame sequence, go into the static directory and create a file called endgame.flg. In it, put the string "Congratulations!" and run u7p2. It's really good! -- tmcreek@eos.ncsu.edu \ These views respresent no one. / Now you creek-tm@aza.csc.ncsu.edu \ Even I won't claim them. / are here ---------------------------------------------------------------------------- #include "std_funny_stuff.h" /* This is where I include some witty tripe */ ------------------------------ Date: Tue, 30 Mar 1993 11:44:00 -0800 From: john.smith@gravis.com (John Smith) Message-Id: <733534174.AA01830@ship.net> Subject: ULTRASOUND 03/30/93 1/2 To: Ultrasound Daily Digest UltraSound 03/30/93 ------------------- 1) A few days ago I posted a long tech note from Gravis and Forte. The last line of that message said, "5) Being overly critical of a $150 sound card....". This was suppose to make you laugh! I've heard from a few people who didn't find this very funny. Yes, we do make attempts at a little humor now and then. ;-) 2) There has been a discussion over the last few weeks about recording silence with the GUS card. People have been complaining of popping or static periodically. Here are the results of some testing I've done. To test the recording of silence I shorted out line in and mic in using two phono plugs. NOTE: You can short our your GUS inputs but NOT the outputs, line out, or amp. line out. I used PLAYFILE and USS8 to handle the recording and both returned the same results. The 'static' you are hearing is due to a 1 bit variance in the recording. Silence should be recorded as DC offset 0 (7Fh) on the UltraSound. A +-1 bit variance is actually very good for an AD converter. Even a +-2 bit variance is ok. When recording silence your ear is very sensitive to any shift in the noise pattern. Which is why this your ear can pick up this bit difference when silence is recorded. In the test files I did, over 95% of it had a DC offset of 0. There were only small sections of the file that had small periods of this 'static' (+-1bit). Remember, this is only noticeable when recording silence. If you are recording noise you wouldn't be able to hear this small of a difference. A couple things to keep in mind though: EMM386 or any memory manager will affect your recording performance. A disk cache will help your performance. Make sure your hard disk is not overly fragmented. Mic in will cause more noise than Line in due to the fact that it is amplified. Even with a 16bit recording card you will still get this variance. However, it should be less noticeable due to the larger sampling window. For those of you who want to test this, try creating a file full of 7Fh. Make sure you use a hex editor and not a text editor. You may then use PLAYFILE to play it back. Now go in there and change a few bits to either 7Eh or 80h and hear the difference it can make. 3) Boy did I screw up. It seems in our "Authorized Gravis Nodes" list I put my home phone number in there as the Gravis BBS phone number. Guess that explains why I was getting calls at 3am .
